Twilio-Zoho CRM SMS Integration

Is it still possible to integrate the Twilio SMS function with Zoho CRM? The directions provided on the Zoho on the help site have me stuck at the marketplace in CRM because there is no Twilio extension there (https://www.zoho.com/crm/help/extensions/twilio.html). I also looked on Zoho's marketplace but the option is only available for Zoho Recruit.
